SEWING-MACHINE ATTACHMENT.

To all whom it may concern:

Be it known that I, ALBERTO MEMOLI, a cit- I izen of the Republic of Brazil, and a resident of New York, borough of Brooklyn, county of Klngs, and State of New York, have invented certain new and useful Improvements in Sewing-Machine Attachments, of which the following is'a specification.

My invention relates to sewing machine attachments, and more particularly to an attachment for facilitating the sewing of an edge seam without basting the fabric in.

place.

Other objects, features and advantages of the invention will appear more fully 1n the following specificati0n and appended. claims. i In order'that the'invention may be more clearly understood attention is hereby di rected to the accompanying drawing forming a part ofthis specification and illustrating one embodiment ofthe invention. In the drawing,

Figure 1 1s a plan view illustrating the use of the invention in sewing an edge seam.

Fig. 2 is a view of the same partly'i'n elevation and partly in section taken alon lines 2-3 of Fig. 1,'the fabric to be stitched being, however, omitted.

Fig. v3 is a plan view of the same arranged for stitching an edge containing a rentrant angle. v

Fig. 4: is a fragmentary front view on an enlarged scale.

To facilitate an understandin of the invention,'a brief description will rst be given of the ordinary edge seam used in a garment such as a coat. In making such a seam, two layers of fabric are superposed with their front faces in contact and are then stitched together by a machine close to their edges. The fabric article thus produced is then turned inside out so that the front or outer faces of the fabric are outermost, the edge portions of fabric being pressed down by the fingers so as to bring the line ofstitching substantially at the edge of the article. Fig.

4 shows the fabric in this condition and held in place to permit the sewing machine needle to stitch downthe edge portion of the article into final shape. In the said figure, a and b representthetwo layers of fabric which have inwardly turned flange-like portions 0 and (Z connected by the line of stitching 6 which secures the two layers of fabric together prior to the final stltching of the edge seam. e

Application fil ed April 24, 1919. Serial No. 292,293.

Ordinarily after the edge of the article is arranged as shown in Fig. A it is held in place during stitching by the sewing machine by basting. My lnvention obviates the necessity of such basting and permits the fabric to be fed directly to the sewing machine needle for the outer stitching of the edge seam after the two layers of fabric have been turned so that the finished front faces are outermost. My invention at the same time secures results in evenness of stitching which are superior to those obtamed1 where the basting operation is emp o e a eferring to the drawing, the invention comprises a gage 1 for facilitating the positioning of the fabric with respect to the needle 2 so that the latter will operate upon r the fabric article at a uniform distance from and held in such sha e while it is being acted upon by the nee 1e. This last named device, as shown, is in the form of a tapering finger 3 projecting forwardly from the presser foot 4 of the sewing machine and extending a considerable distance forwardly of the needle 2. The finger 3 is arranged with its axis parallel to the line of feed of the fabric through the machine and the guiding edge of the gage, the taper of the finger being such as to press the edge of the fabric with gradually increasing pressure to force the same into shape for receiving the outer row of stitching from the sewingmachine.

The taper of the, finger 3 also serves to press the fabric firmly over against the guiding edge of the gage 2, the edge of the fabric, as shown invFig. 4 being somewhat thicker than the portion arranged inwardly of the same. To facilitate proper positioning of the finger 3 with respect to the fabric and the gage 1, the finger is mounted so as to be laterally adjustable. As shown, the finger 3 is mounted upon plate 5 which is adapted to slide laterally upon the presser-foot 4;, the plate 5 being provided with an elongated slot 6 extending transversely to the axis of finger 3, and being secured to the presser-foot 4 by means such as the screw 7 passing through the slot 6. The presser foot shown is adapted to be attached to a sewing machine in place of the usual presser foot. It is provided at its upper end with a slot 8 through which an attaching screw is adapted-to be from the needle.

passed, the slot furnishing vertical adjustment of the presser foot.

The gage 1, as shown, is made adjustable toward and away from the needle 2, as is usual. As shown, the gage 1 is provided with an elongated slot 9 extending at right angles to the line of feed of the sewing machine and is detachably secured to the baseplate 10 of the sewing machine by screws 11 and 12 passing through the slot 9, these screws being arranged so as to permit a movement of the gage toward and away My improved gage is provided with a second gage member 1 1 which is movably mounted upon the gage 1 so that it may be arranged with its operative or guiding edge 15 in alinement with the operative or guiding edge of the gage 1 or moved into inoperative position as shown in 1 ig. 3 to facilitate sewing a seam in an edge containing a reentrant angle. When. arranged as shown in Fig. 1, the gage memhers 1 and 141 provide a long guiding edge which is very eflective in sewing a straight seam of considerable length; and w'henan ranged as shown in Fig. 3, the part 14 is moved out of the way so as to form no obstruction to the projecting part of the fabric such as the lapel Z, the gage member serv-- ing as a guide for the fabric almost to the apex of the reentrantangle and the lapel passing into the angular recess of the gage 1 between the elongated portion 16 and the baseportion 17. As shown, the member 14 is connected to the gage 1 bya screw 18 passing through aslot 19 in the member 14, which slot permits adjustment of the member 14 so as to bring edge 15 in alinement withthe guiding edge of the gage 1.

In use,,the fabric article having been stitched as shown at e, the edge of the fabric article is pressed down somewhat between the fingers so as to bring the same approximately vinto shape and placed under the presser foot. The machine having been started, the fabric article is fed past the sewing machine needle 2, the edge of the article being guided by hand toward the gage and being pressed firmly against the latter by the finger 3 as'the fabric is fed to the needle upon the movement of the usual feeding member, which is shown at 20 in Fig. 2. During this operation the finger 3 presses V the edge portion of the fabric article gradually into shape and holds the same in shape while the needle 2 is operating upon the same; and an even seam is obtained at the edgeof the article. Not only is the operation of basting the edge of the fabric eliminated but an'additional saving of time is effected with my invention because there is no need of removing the bastingafter the edge has been sewed by the sewing machine. While I have shown one embodiment of my invention, it is to be understood that I is as follows:

am not limitedto this embodiment; and mu merous changes and modifications maybe made in the device herein shown without departing from the spirit of my invention. What I claim as new and desire to protect by Letters Patent of the United States 1. The combination of a fixed gage having a guiding edge and a projection of considerable length extending approximately parallel to said edge to press upon the material as it advances to a sewing machine needleand to hold the same compressed at a point in proximity to the'sewing machine needle, said projection being tapered to cause the material to be gradually pressed to opera-: tive relation tothe needle and gage to permit sewing an edge seam without basting.

2. The combination with sewing machine mechanism including a presser foot, needle, and feeding mechanismof a member carried by the presser foot and extending a con- .siderable distance forwardly of :the needle,

said member being arranged to; press upon the material as it advances toward the needle and to hold the same compressed in the vi cinityof the needle, and a fixed gage adapted to be engaged by the edge of the material said member being adapted to press the ma terial with gradually increasing pressure toward said gage to facilitate the stitchin g of the material a uniform distance from the edge thereof to form an edge seam without basting. V

3. The combination with sewing machine mechanism including a presser foot, needle, and feeding mechanism, of a member car-- ried by the presser foot and arranged to press upon the material with gradually inl creasing pressure as it advances toward the needle and to hold the same compressed in the vicinity of the needle, and a normally fixed gage mounted for adjustment toward and from the needle, and adapted to be engaged 1 by the edge of the material to facilitate 11 the stitching of the material a uniform distance from the edge thereof, said member being arranged to force said moving material a ainst said gave to permit sewing an edge seam without basting. 1
